Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, specifically to a rotating fixture for spraying automotive exterior panels. Background Technology

[0002] Spray painting is one of the important processes in automobile manufacturing. It is mainly used to treat the exterior parts of automobiles, such as the frame, doors, bumpers, and exterior trim. As external parts that are connected to the car body by bolts or clips, they serve to decorate and protect the vehicle. Their appearance quality directly affects consumers' overall evaluation of the car. Chinese patent CN223171163U discloses a jig for spraying automotive interior plastic products, including a worktable, a connecting plate fixed to the worktable, a servo motor mounted on the connecting plate via a mounting bracket, a first clamping bracket connected to the output shaft of the servo motor, a first clamping bracket having symmetrically distributed clamping slots, a second clamping bracket hinged to the first clamping bracket via a hinge, and a threaded mounting bolt on the second clamping bracket. The servo motor on the first clamping bracket can drive the steering wheel to rotate, facilitating all-around spraying and ensuring that the paint can be evenly covered on the outer surface of the steering wheel, thus helping to improve the quality and appearance of the coating. However, the following shortcomings still exist: During the painting process of automotive exterior panels, a large amount of paint residue remains on the workbench. However, during the cleaning process, it is difficult to remove the attached paint residue by manual cleaning alone. Over time, this residue accumulates and forms stubborn dirt, affecting the flatness of the subsequent placement of the exterior panels. The residual liquid and impurities are prone to sticking together, which not only leads to deviations in workpiece positioning accuracy and indirectly affects the uniformity of spraying, but also causes the residual paint to harden after drying. If it accidentally comes into contact with the painted surface of the exterior panel, it will damage the integrity of the coating and affect the appearance quality. Therefore, those skilled in the art provide a rotating fixture for painting automotive exterior panels to solve the problems mentioned in the background art. Utility Model Content

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figures 1-6 As shown, this utility model provides a technical solution: a rotary fixture for spraying automotive exterior panels, including a support component 1 with a worktable 101 inside, a power component 2 for outputting driving force on the support component 1, a clamping component 3 for clamping and fixing the automotive exterior panel on one side of the power component 2, and the clamping component 3 for clamping the automotive exterior panel and driving the workpiece to rotate under the drive of the power component 2, and a cleaning component 4 for cleaning the residual material on the surface of the worktable 101 inside the support component 1; As one implementation method in this embodiment, please refer to Figures 1-2As shown, the support assembly 1 includes a workbench 101, a support vertical plate 102 is fixedly installed on one side of the upper end of the workbench 101, an mounting base 103 is fixedly installed in the middle of the rear of the support vertical plate 102, a collection box 104 is fixedly installed at the front end of the workbench 101, and a plug cap 105 is movably installed on the lower end of one side of the collection box 104. Furthermore, the workbench 101 serves as the supporting base for the entire support assembly 1, used to place the automotive exterior panel to be painted, and also provides a fixed mounting surface for components such as the support vertical plate 102 and the collection box 104, ensuring the positional accuracy of each component. The support vertical plate 102 provides a stable mounting carrier for the mounting base 103 through its vertical layout, and forms a vertical support structure with the workbench 101 to bear the weight of the rotating mechanism and the exterior panel. The collection box 104 is used to collect excess paint dripping or splashing during the painting process, preventing paint from contaminating the workbench 101 and the ground or causing waste, while keeping the working environment clean. The plug cap 105 serves as a sealing and discharge component for the collection box 104. When normally closed, it can prevent paint leakage from the box, and when opened, it can quickly discharge the collected waste paint, facilitating subsequent cleaning and recycling.

[0018] As one implementation method in this embodiment, please refer to Figures 2-4 As shown, the power assembly 2 includes a motor 201, which is fixedly installed on the upper end of the mounting base 103. The drive end of the motor 201 is rotatably connected to a rotating disk 202 near the center of the front of the support vertical plate 102. One end of the rotating disk 202 is fixedly connected to a fixed bracket 203. The clamping assembly 3 includes two sheet metal parts 301, which are fixedly installed on both sides of the fixed bracket 203. Each sheet metal part 301 is equipped with two cylinders 302. The telescopic ends of the two cylinders 302 are fixedly installed with connecting plates 303. Support plates 304 are fixedly installed on both sides of the two connecting plates 303. Each set of support plates 304 is equipped with a cylinder 305. The telescopic ends of the two sets of cylinders 305 are fixedly installed with clamping plates 306. Furthermore, when the operator places the exterior trim panel to be painted in the designated position between the two sets of clamping plates 306, the telescopic end of cylinder one 302 extends or retracts, adjusting according to the width of the trim panel. This, via connecting plate 303, drives the side support plates 304 to move laterally, causing the two sets of clamping plates 306 to initially approach the two sides of the trim panel in the width direction. Subsequently, the telescopic end of cylinder two 305 extends, pushing the clamping plates 306 longitudinally to clamp the surface or edge of the trim panel at the pre-reserved clamping position until the preset clamping force is reached, completing the secure clamping of the trim panel. After clamping is complete, the motor is started... Force component 2, motor 201 starts at a preset speed, drive end drives rotating disk 202 to rotate smoothly, rotating disk 202 drives the entire clamping component 3 and the clamped exterior panel to rotate synchronously through fixed bracket 203. During rotation, the spraying equipment sprays the rotating exterior panel. Since the exterior panel rotates continuously and at a uniform speed, the nozzle does not need to frequently adjust the angle to cover multiple positions of the exterior panel, achieving all-round uniform coating. The speed of motor 201 can be flexibly adjusted according to the type of paint and the coating thickness requirements to ensure paint leveling and coating uniformity.

[0019] As one implementation method in this embodiment, please refer to Figures 2-6 As shown, the cleaning component 4 includes a liquid storage tank 401, which is fixedly installed on the upper end of the workbench 101 near the mounting base 103. A water pump 402 is installed near the edge of the upper end of the liquid storage tank 401. Baffles 403 are fixedly installed on both sides of the upper end of the workbench 101. A guide groove 404 is opened in the middle of the interior of each baffle 403. A telescopic pipe 405 is fixedly connected to one side of the guide groove 404 near the upper end of the water pump 402. The telescopic pipe 405 extends through the support vertical plate 102 to the support vertical plate 103. 2. At the front, a control plate 406 is fixedly connected to one end of the telescopic tube 405 near the upper end of the workbench 101. A scraper 407 is fixedly connected to the bottom surface of the control plate 406. Guide tubes 408 are fixedly installed on both sides of the scraper 407. Several balls 409 are movably installed inside the two guide tubes 408. The scraper 407 and the balls 409 are in contact with the top surface of the workbench 101. Guide blocks 4010 are snapped into the two guide grooves 404. A control handle 4011 is fixedly installed on one side of the guide block 4010. Furthermore, the water pump 402 draws liquid from the storage tank 401 and delivers it to the guide pipe 408 through the telescopic pipe 405. The operator holds the control handle 4011 and pushes and pulls the control plate 406. At this time, the guide block 4010 slides linearly along the guide groove 404 of the baffle 403. The stroke and speed can be flexibly adjusted to drive the scraper 407 to move synchronously. The bottom surface of the scraper 407 is in close contact with the top surface of the workbench 101, scraping away impurities and residual liquid on the workbench. At the same time, the ball bearing 409 rolls with the scraper 407. During the rolling process, the ball bearing 409 carries out the cleaning water in the guide pipe 408, so that the scraper 407 can wipe away the hard-to-scrape paint on the workbench with cleaning water while scraping, thus effectively cleaning the workbench 101.

[0020] Working principle: The workbench 101 supports the base of the support assembly 1, on which the outer trim panel to be painted is placed. It provides an installation surface for the support vertical plate 102, the collection box 104, etc., to ensure positional accuracy. The support vertical plate 102 supports the vertical support mounting base 103, forming a vertical structure with the workbench 101, and bears the weight of the rotating mechanism and the outer trim panel. The collection box 104 collects excess or splashed paint, preventing pollution, reducing waste, and keeping the environment clean. The plug cap 105 seals the collection box 104 to prevent leakage. It can be opened to quickly discharge waste paint, which is convenient for cleaning and recycling. The operator places the exterior panel to be sprayed in the designated position between the two sets of clamping plates 306. Cylinder 1 302 extends and retracts according to the width of the exterior panel, and drives the support plate 304 to move laterally through the connecting plate 303, so that the clamping plates 306 are close to both sides of the exterior panel. Then, cylinder 2 305 extends and pushes the clamping plates 306 to clamp the exterior panel longitudinally, completing the secure clamping. After starting the power component 2, the motor 201 drives the rotating disk 202 to rotate at a preset speed. Through the fixed bracket 203, the clamping component 3 and the exterior panel rotate synchronously and uniformly. The spraying equipment operates synchronously, and all-round uniform coating can be achieved without frequent adjustment of the spray nozzle. The speed of motor 201 can be flexibly adjusted according to the paint type and coating thickness to ensure paint leveling and coating uniformity. The water pump 402 draws clean water from the storage tank 401 and sends it to the guide pipe 408 through the telescopic pipe 405. The operator holds the control handle 4011 and pushes and pulls the control plate 406, which drives the guide block 4010 to slide linearly along the guide groove 404 of the baffle 403. The stroke and speed can be flexibly adjusted. At the same time, the scraper 407 is driven to stick to the top surface of the workbench 101 to scrape away impurities and residual liquid. Meanwhile, the ball bearing 409 rolls with the scraper 407, bringing out the clean water in the guide pipe 408, so that scraping and wiping with clean water are carried out simultaneously, and the workbench 101 is cleaned efficiently.

[0021] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
